Answer
Igipimo cyimpeshyi $ k $ kumpinduka nyinshi Crest-to-Crest umuraba wamasoko ukomoka kumata $ k = \ frac {E \ cdot b \ cdot t ^ 3 \ cdot N} {D_m ^ 3 \ cdot Z ^ 4} \ cdot \ frac {4 \ cdot Z} {N} $, aho $ E $ ari moderi ya $ b $ $ N $ numubare wimpinduka, $ D_m $ nigipimo cya diametre, naho $ Z $ numubare wumuraba kumurongo. Uburinganire mumurongo-wo gutandukanya umurongo bugumaho hagati ya 20% na 80% yo gutandukana kuboneka. Kurenga 80%, ingaruka 'gutembera' ibaho aho imiraba itangiye gukoraho, itera kwiyongera kugaragara $ $ $. Ibinyuranye, mugihe gito (<20%), igipimo gishobora kuba gito kubera gutangirira kwambere impinga yumuraba hejuru yubusabane.
